Howe Caverns is a premier natural attraction, a living, limestone cave, carved by an underground river over the course of 6 million years, located 156-feet below the earth's surface. An Schoharie County, N.Y. farmer discovered the caverns more than 160 years ago. Formed in 1927, Howe Caverns incorporated, a public company owned by shareholders, opened the caverns to the public on Memorial Day weekend of 1929.
